Ultrasonic wind speed measurement device with temperature compensation

The utility model provides an ultrasonic wind speed measurement device with temperature compensation. The structure of the ultrasonic wind speed measurement device comprises an ultrasonic speed measurement device (1), an ultrasonic transmitting end (2), an ultrasonic receiving end (3), a wind speed displayer (4) and a wind speed LED dial (5). The sonic wave wind speed measurement device system is composed of a processor MCU (6), an ultrasonic generator (7), an ultrasonic receiver (8), a bluetooth BLE (9), a temperature sensor (10) and a power supply management circuit (11). Sonic wave has the Doppler effect in the flowing air with reference to speed of sonic wave in the air under different temperatures, and wind speed is measured according to phase difference brought by the Doppler effect. The characteristics of low cost, low power consumption and portability can be realized by the device.
